Is there any chance that "L'Huitre et les Plaideurs" belongs to one of the two earlier sets (1883 and 1896) of La Fontaine’s fables in the Liebig series? Might Liebig have sold the plates from its cards for use by others? "Le Lièvre et les Grenouilles" even has the title bar across the top in which "Vero Estratto di Carne Liebig" appears in the 1900 series. The colors have dulled on these cards. They are in fair to good condition.
